Oil-water separation device for separating and recycling edible oil

Abstract

The invention discloses an oil-water separation device for separation and recovery of edible oil, which comprises a casing, a feed inlet arranged on one side of the upper part of the casing, and inside the casing, a plurality of choke columns are evenly distributed below the feed inlet. A plurality of blocking columns form a comb column array, and a wave-shaped anti-wave plate is provided between the comb-column array and the water outlet. The upper part of the anti-wave plate is provided with an overflow port. There is a sloping plate below the mouth, and an oil absorbing device with a hydrophobic oil-absorbing sponge is arranged above the sloping plate. The end of the sloping plate is connected to the water outlet, and the oil absorbing device is used to absorb oil on the sloping plate. The oil-water separation device of the present invention can better promote oil-water stratification and separate oil-water. After being absorbed by the oil-absorbing device, the separated oil has a high concentration and very little water impurity content, which greatly reduces the post-treatment of recovered oil. Continuous oil-water separation can be realized, the oil-water separation efficiency is high, and the manufacturing and use costs are relatively low, which is conducive to market application.

Description

technical field [0001] The invention relates to the field of oil-water separation equipment, in particular to an oil-water separation device for edible oil separation and recovery. Background technique [0002] Nowadays, the production of domestic sewage is increasing, especially the sewage containing a large amount of edible oil produced by restaurants. The country stipulates that the oily sewage in restaurants must be separated from oil and water before it can be discharged to the outside. However, the existing equipment is It is the primary separation of oily sewage, and there is still a layer of oil film floating in the discharged sewage. At present, there are few devices for oil film separation, and the manufacturing and use costs of these devices are relatively high. Therefore, they are limited by market prices. . [0003] Chinese patent CN103073091A discloses an oil-water separation device for thin oil film separation and recovery. Its characteristics are: a box cove...

AI Technical Summary

Problems solved by technology

However, since the oil and water in the housing cannot pass through the array of comb columns to achieve a better static state, the oil on the upper layer of the water fluctuates greatly, which is not conducive to the thickening of the oil film and the discharge of the final oil.

At the same time, when the solenoid valve discharges oil, the oil still contains a lot of water, resulting in a low oil concentration when recovering oil, which is not conducive to the recovery of oil in the later stage
